Initial analysis

The 3515-3517 Judah Street property is a two-unit, two-story multi-family residential building constructed in 1947, currently owned by the Yuan Family Revocable Trust. The building has faced several significant maintenance and safety issues over recent years, with the most pressing concerns emerging from active complaints filed in December 2017 and March 2023. The 2017 complaints revealed multiple violations including lead paint hazards, plumbing discrepancies, and safety issues such as the need for fire extinguishers, carbon monoxide detectors, and smoke alarms. More recently, in March 2023, complaints surfaced regarding water leaks potentially endangering the building's structural integrity in the second-floor apartment, along with issues relating to weatherproofing and stair repairs. The property has undergone some maintenance work, including a $20,000 project in 2023 to address issues with the building's exterior paint, siding, and staircase dry rot. There are ongoing concerns about basic safety compliance, as evidenced by the active nature of these violations and complaints.

The building's maintenance history includes several attempted improvements and repairs, with varying degrees of completion. Notable attempts to address code violations occurred in 2018, including efforts to legalize non-conforming units and remodeling work estimated at $20,000. More recent plumbing work was performed in 2023, involving water heater replacement and leak repairs, though this permit has since expired. The property has been subject to regular maintenance needs, including a complete reroofing project in 2003 and a furnace replacement in 2014. Looking ahead, significant proposed changes are currently under review that could substantially alter the property, including the addition of units on multiple floors, new exit passageways, rebuilt stairs, and improved bicycle storage facilities. This proposed development represents the most substantial potential change to the property since its construction in 1947.

Risk rating

How 3515-3517 Judah St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
